We no longer have the ‘have-the-job-but-can’t-get-it-done-in-time’ issue. Lead times are 30–50% less.
— Brett Keene, CEO, Suttle-Straus
A selection of forms transfer carts provides easy-to-use and flexible stack transportation to match your environment.
The AutoLoad f4 HS system allows you to print and insert longer without stopping, by creating efficient, high-capacity stacks. Run times are extended while printing bills, statements, checks or other transactional mailing applications, and output can be presented A-Z or Z-A as needed. There are five StackRack™ transfer carts to choose from, holding up to 40,000 forms, for space-efficient forms movement and storage, and for feeding stacks to inserters.
The AutoLoad f4 HS system is comprised of the Folder f4 HS, the Table HS and the AutoLoad Tilt Table t3, along with the Unwinder u50. Once material is printed and fanfolded, folded output cascades onto the AutoLoad Tilt Table t3, which works in conjunction with the Folder f4 HS to accept fanfold stacks and offload forms for insertion.
All components use standard power, are mobile, modular, compact, and are designed to dramatically improve workflow.

Modular System Options
Table HS
The Table HS is a non-powered table with a pivoting table top surface to allow for easy adjustment for A‑Z or Z‑A processing. The Table HS is recommended for high-speed operation, over 500 to 600 fpm, to allow for greater system capacity before filling.
StackRack Carts
A variety of StackRack carts are available to hold and transport up to 40,000 forms for continuous feeding of high-speed inserters.
Inserter Infeeds
Ensure smooth and reliable paper flow. Passive or powered models to match your inserter.
